Why does my computer have no screen when it is turned on

After the computer is turned on or restarted from the computer, the start menu, taskbar, and desktop icons are gone, sometimes caused by misoperation, but most of them are due to viruses in the computer, and the virus has been modified, so the start menu, taskbar and desktop icons are gone, and the processing method is as follows:

The processing method is as follows:

Step 1: If it is accidentally removed, that is, it is misused: the solution is to disappear the desktop icon, you can:

Right-click on the desktop, select "Arrange icons" - show desktop icons", and check the display desktop icons. If you have lost the main icons such as "My Computer", "Internet Neighbor", "Internet Explorer", etc., you can right-click the desktop, select "Properties", and then select "Desktop" - "Customize Desktop", put a checkmark in front of the icons you just lost, and click OK. For the disappearance of the start menu and taskbar, you can click the control panel taskbar and start menu taskbar to automatically hide the taskbar, remove the previous checkmark, and the taskbar will appear, and tick the lock taskbar, click Apply, OK, and this taskbar will not disappear easily in the future.

This is mainly due to the virus deleting or tampering with the core files of the system, or the virus is directly deleted or infected with the virus and killed by the antivirus software.

The solution is: you can press Ctrl+Alt+Delele keys, and then the task manager will pop up, then click File, then create a new or add a task, enter, and then OK. In this way, the taskbar and desktop icons are all out, and it is OK to restart the computer (illustrated in the following two pictures).

Step 3: There is another solution: if QQ PC Manager is installed on the computer, you can use the "Computer Clinic" function in the PC Manager to solve the problem of abnormal desktop icons and system fonts in the XP area.

If the above three steps are still not normal, you can only restore it with one click, or reinstall the system with a disc or USB flash drive, so that it can be foolproof.
